PLEASURFRAILROAD.

SPECIFICATION forming part of Letters Patent No. 739,1 69, dated September 15, 1903.

Application filed Marchl, 1903.

loop portion is portable and is constructed to f.

be hauled in the street-parade. y

Another object is to design a light carriage for holding a monkey, which carriage will be provided with guide-shoes located to engage parallel guides mounted ou the inclines and spiral loop.

The simple and novel construction adopted by me to attain these objects is vfully described and claimed in this specification and illustrated in the accompanying drawings, forming a part thereof, in which- Figure l is a side elevation of my complete device. Fig. 2 is a detail edge View of the spiral loop. Fig. 3 is a detail front elevation of the cross-bar and inclined locking members. Fig. 4 is a side elevation of the same with runway. Fig. 5 is a transverse section ofone of the inclines, showing the guides in section.

Fig. 6 is a detail side elevation of the carriage.

Like numerals of reference designate like parts in the different views of the drawings.

The numeral 1 designates a substantially square frame having four sides 2 tied together by four braces 3, extending diagon-V ally the corners. Mounted within the frame 1 is a turn and a quarter of a circular spiral runway 4, terminating in upwardly-inclined straight portions 5 and 6. The spiral4 comy prises spiral side rails 7 connected by cross-- ties 8, on which a iioor 9 is laid and forms the inner surface of the runway. Parallel guide-rails 10 are mounted intermediate the side rails 7 and arerigidly attached to the floor, thereby forming a guide-groove 11 of uniformwidth. To render theloop 1 portable, a running-gear 12, provided with four wheels 13 and a pole 14, is provided, which Serial No. 148,018. (No model.)

running-gear serves to carry the loop, which can be easily and quickly moved by bitching two ponies to the pole 14.

In order that the carriage may gain sufficient momentum to enable it to round the loop 1, an incline 15 is connected to the short incline 5, which connects with the spiral 4, and to enable the carriage to slow down an incline 16 is connected to the short incline 6, which connects with the other end of the spiral 4. The inclination of the incline 15 is about forty-tive degrees; but the inclination of 16 is about half as much. Both of the inclines 15 and 16 are constructed of sections 17 of convenient length, supported by posts 18, sustained by guy-lines 19, secured to pins or stakes at the sides of the inclines. A crossbar 20 is secured to the head of the posts 18 vand has equal arms 21, held rigid by braces 22. Locking members 23 are mounted transversely the outer ends of the arms 21 and are set at an inclination Vequal to that of the sections 17 of the inclines.

A light carriage'26 is provided to run on the runway. It has four unlanged wheels 26a and carries two guide-shoes 27 and 28, mounted on the front and rear, respectively, of the bottom of the carriage and extending down and iitting loosely the guide-groove 11, intervening between the guide-rails 10. Flanges 27a and 28, formed on the shoes 27 and 28, respectively, bear on the tops of the guides 10 and hold the carriage against wabbling.

In operation the device is set up as shown in Fig. 1, the carriage 26 set on the upper end of the incline, and a monkey or other animal placed therein. The shoes 27 and 28 are engaged in the groove 11, after which the carriage is released, when it will descend the incline 15, traverse the loop, and then run up the incline 16 and gradually come to a stop. The shoes 27 and 28 serve to guide the earriage and compel it to take the loop without leaving the runway. After the performance has been concluded the sections 17 are disengaged from the lugs 24, the posts 18 un- ICO guyed, and the inclines removed, after which the loop l can be hauled out.

I do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a loop-the-loop device, the combination with a spiral loop, of two inclines connected to opposite ends of the spiral, parallel guide-rails mounted on said spiral and said inclines with an intervening slot extending continuously from one end of one of the iuclines to the opposite end of the other inoline, and a carriage having unfianged wheels and bearing a shoe engaging said groove to thereby constrain the carriage to follow said inclines and said loop, substantially as described.

2. In a loop-the-loop device, an inclined runway formed of abutting sections havingv recesses or sockets adjacent to their ends, posts having inclined heads bearing lockinglugs tting said recesses, substantially as described. l

3. In a 1oop-theloop device, an inclined runway formed of abutting sections having recesses on their under sides, posts bearing inclined locking members provided with lugs fitting said recesses, and means for guying said posts, substantially as described.

4. In a looptheloop device, the combination of a post bearing oppositely-extending arms, locking members inclined to the horizontal and mounted transversely said arms, a runway formed in sections having recesses therein near their ends and engaging said lugs, and guy-ropes connected to said posts and detachably secured'to the ground, substantially as described.

5. In a loop-the-loop device, the combination of a spiral runway, two inclines connected to said spiral, parallel guides mounted centrally said runway, a carriage having unflanged Wheels, and two shoes mounted on the front and rear, respectively, of said carriage and engaging the guide-groove intervening between said guides, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
